A former trauma nurse has been sentenced to 20 years in prison for a drunken driving crash that killed a reservist from Hurst two years ago.

TheFort Worth Star-Telegram reported that Beth Branum, a 31-year-old mother of three, received the maximum sentence after being convicted of intoxication manslaughter on Tuesday.

Authorities say Branum was drunk when she sped through a red light in Euless and rammed into the car of Brandon Bennett about 5 a.m. March 9, 2014.

Bennett, 20, was headed to Lewisville for drills with the Texas Army National Guard. He died at a hospital two hours after the crash.

Branum did not have any prior felony convictions, but she did have other run-ins with authorities, according to the Star-Telegram.

She racked up 10 misdemeanor traffic citations -- including speeding and driving without a license plate -- between 2009 and 2013.

After the 2014 crash, Branum tampered with her alcohol sensor at least three times while out on bail, according to testimony.

Her bail was revoked, and the tampering was used against her in trial to show she was not suited for probation, the Star-Telegram reported.

Bennett, the victim in the crash, hoped to become a police officer and a father.

At Branum's trial, Bennett's mother described the anguish that followed his death.

"It was the worst nightmare a parent could ever see," Branda Holden testified, according to the Star-Telegram. "I opened the door and saw two police officers and a chaplain. I didn't understand. It was a residential area. How could this happen where my kids grew up?"
